In a joint letter submitted by Huff and Savage, the two said they used their business experience and leadership to further the airport and make the region stronger. They said they hope their resignations allow the board “to address the many challenges and opportunities that lie ahead.”

Arnzen resigned after learning about Huff and Savage’s letter. He said he was resigning to support the others.

Arlinghaus accepted the resignations and appointed Bill Robinson III, Kathy Collins and Chad Summe in the vacant positions.

Arlinghaus said the appointments accomplished two objectives he has for the airport board.

“These appointments fulfill two of my primary goals: all three new appointees work in Cincinnati businesses, which assures that the Cincinnati business community will have a stronger voice on the airport board, and the appointment of Kathy brings more diversity to the airport board,” Arlinghaus said.
